Bon 11S, Sidney, 1iowa Filed Bec. 11i, 1%2, Ser. No. 243,471 1 Clmm. (El. Z39- 441) My invention relates to a combination water directing nozzle. Y

An object or my invention is to provide a combination nozzle which will electively provide a fog arrangement or a straight stream arrangement or a spray arrangement.

A further object of my invention is to provide adjusting means, and to provide an arrangement which can be readily altered to suit the required conditions, etc.

A further object of my invention is to provide a special arrangement whereby certain parts of the device can be changed from the straight stream arrangement to the spray arrangement without removing, or re-placing, any

of the parts, and whereby such change can be eected by a simple rotary movement.

A further object of my invention is to provide an arrangement which will provide a hollow cone-shaped fog, with adjustments as desired, or Which will provide a solid type of, spray cone.

A further object of my invention is to provide a unit which can be conveniently carried by the fireman, and which is not too large or bulky, and yet which will provide all of the above mentioned results.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts or my device, whereby the objects contemplated `are attained, asl hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawingsn which:

My invention contemplates the provision of a changeable and adjustable device which, when fighting a re, will provide means for shifting the nozzle unit to accommodate a variety-of conditions.

In describing my invention I have used the character 1G to designate a coupling which is threadably engaged at 11 with the standard threaded end 12 of a hose member 13 which is attached to the hose 14 and which hose is to feed the water supply to the nozzle, and threadably engaged with the member 1li at 15 is an elongated pipe 15 which pipe 16 extends throughout the arrangement and is threadably engaged at 17 with a housing 1S. The member 18 includes a ball 19 attached to a stem 2li which is attached at 21 to a control lever 22, the ball 19 including a port 23 adapted to communicate with the passage-way 24 and the further passage-way 25, the

character 26 indicating a compression spring for holding the valve ball in place, and I have further used the character 27 to indicate a further housing or hollow casing having a series or" peripherally arranged openings l satana Patented Dec. 29, l94` "rice 2S passing therethrough, and I have further used the character 29 to indicate a series of peripherally arranged prongs being `bent into the outwardly extending portions 39, the prongs 29 being threadably engaged as at 31 with the casing wall 217.

The character 32 indicates a collar rigidly attached as at 33 to the pipe 16, the character 34 indicating a pair of links being pivotally attached at 35 to the substantially U-shaped lever 36, the lever 36 being pivotally attached as at 37 to the collar 32, the links 34 being pivotally attached Vat 3,8 to a further U-shaped lever member 39 which is attached solidly as at dit to a further collar member 41 which -is suitably secured to a further member 42.

The member 42 is secured by means of a suitable set screw 43 recessedin the opening 44 and which set screw bears against the cylindrical sleeve 45 which receives the pipe :16, the sleeve 4S being secured to the member 42, and the member 42 includes an annular channel e6 which communicates with a series offperipherally spaced openings 47 which terminate at 4S.

Threadably engaged with the tube 45 at 49 is a substantially cylindrical member Sil through which the tube 16 passes, and the member 5@ includes a portion 51 which is beveled at 52, and is adapted to coincide with the beveled portion 53 of the member 52.

IV have further used the character 54 to designate a further collar member which can be adjustably set by means of a set screw 55 on to the member Sli, the member 54 including a plurality or peripherally arranged teeth 56 vhaving the channel portions 57 therein (see FIGURE 3), and the memberv 59 is securely attached to a further collar 5S. y

The pipe 16 includes a series of peripherally `spaced openings 59 which are adapted to communicate with the openings 46 when the lever 36 is forced towards the lever 39. f

The member 27 includes the thumb screws el) bearing againstfthe springs 61, the thumbscrews Gli including the -inner ends 62 threadably engaged with the` member Z1, the ends being receivable within an annular grooved channel 63 which is provided in the member 27. The character 27a indicates outwardly tapering walls in the member` 27.

The nozzle is operated in the following manner. In case it is desired to provide a fog when lightinga tire, and which fog will be-in a substantially hollow conical shape, the fog arrangement is provided by the tapered surfaces 52 and 53, and the lever 36 is forced towards the lever 39 which carries the openings 59 into engagement with the channel 4e so that the water from the hose 14 will be directed through the openings 47 and outwardly along lthese tapered surfaces, the water then being directed against the teeth 56 and the channels S7 whereby the water will then issue in the form of a line atomized spray resembling a fog, whereupon the firemen can advance into the lire with this protection feature.

The set screw 55 allows means whereby the spacing of the member 54 can be adjusted for any desired condition, it being noted also that the rotation of the member 50 by means of the collar 58 along the threads 49 will correspondingly adjust the spacing between the tapered surfaces 52 and 53 so that any desired fog producing arrangement can be provided. Y

For providing a direct stream, the lever 36 can be retracted in the other direction, which brings the openings 59 out of engagement with the channel 46, and the member 27 can be removed by loosening the thumb screw et), whereupon the stream will issue in a straight stream directly through the valve opening 23 and out' through the passage-way 24. s

Also, if it is desired to provide a solid spray cone or 3 water, the member 2'7 is used as shown in FIGURE 1, and with the water passing directly through the tube 16, whereupon the prongs 30 will cause the water to be dispersed and spread, and in combination with the openings 28 which will allow the air to enter into the member 27, the spray effect will be materially increased for this purpose, or if desired, the movement of the lever 36 can provide a combination arrangement. Any number of prongs 30 can be provided, and FIGURES 5 and 6 illustrate the use of the member 27, etc., wherein the same is connected directly to the hose 14, the member 10a indicating a coupling substantially similar to the coupling heretofore described with merely slight modications, and in this arrangement a straight stream can be provided, or the solid conical type of spray. The member 22 provides means for Aturning oit or turning on the Water as required, and it will be noted fromk FIGURE 6 that in this modification more of the members 30 are used.

FIGURES -7 to 10 inclusive illustrate the modied form of the device, and in which it will not be necessary to remove the end piece. In this modification identical characters indicate identical parts, and in this modication the end piece 27 is substantially similar with the following exceptions, however, and in this modification I have used the character 64 to indicate a collar which is attached by means of the screws 65, this collar including a series of peripherally arranged teeth 66 which-are adapted to provide the spray cone effect, and also in this modication I have used the character 67 to indicate a series of rods or prongs terminating in the balls 68, the

prongs 67 also terminating in the portions 69 which are pivotally attached at this point to the casing 27. Engaging the prongs 67 is a rotatable ring-shaped member 70 secured by means of the screws 71, the ring-shaped member 70 including the notches 72 receiving the prongs 67 (see FIGURE 8).

The screws 60 are received within the relatively short arcuate channels 73, and the member 27 is attached to the unit at all times. By merely rotating the casing 27 a slight distance, it will be noted that the prongs 67 will be brought'together, or towards each other, as shown in FIGURE 8, since the engagement ofthe notches 72 with the prongs will cause the prongs 67 to rotate about the point 69, so that in the arrangement shown in FIG- URE 8, the stream impinging against the balls 68 will cause a very nely dispersed spray to be formed, the balls providing the desirable result of dispersing the Water in the desired manner, and 'in combination with the teeth 66. When the unit is rotated in the opposite direction, the collar-70 will correspondingly cause the balls 68 to spread apart as shown in FIGURE 9, thereby allowing the straight stream only to pass through the unit.

FIGURE 10 illustrates a further modification wherein the collar 64, instead of the teeth 66, will include a series of peripherally arranged further balls 74 securely welded or attached to the inner border of the collar 64, which also provides a desirable water dispersing arrangement, either arrangement of which can be employed,

It will now be noted from the foregoing description that my invention provides a variety of conditions and advantages mentioned in the objects of my invention, and it will be understood that other advantages will be inherent in the device also.

Some changes may be made in the construction and arrangement of the parts of my invention Without departing from the real spirit and purpose of my invention, and it is my intention to cover by my Claim any modied forms of structure or use of mechanical equivalents whichmay be reasonably included within their scope.

I claim as my invention:
